Summary of key facts about Asteroid 7 Iris [tip: you can also create a Quick Access page for this data if you access it frequently and would like to have a simpler view]:
- 7 Iris is above the horizon from Greenwich, United Kingdom [change].
- It is visible looking in the East direction at an altitude of 22° above the horizon.
- Given its current magnitude, 7 Iris is visible with the help of a binocular with a 60mm aperture, might require a small telescope.

Asteroid 7 Iris Distance from Earth
The distance of Asteroid 7 Iris from Earth is currently 414,041,467 kilometers, equivalent to 2.767696 Astronomical Units. Light takes 23 minutes and 1.0937 seconds to travel from Asteroid 7 Iris and arrive to us.
The following chart shows the distance of Asteroid 7 Iris from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of 7 Iris from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Asteroid 7 Iris to Earth
Between January 2013 and December 2100, the closest approach of Asteroid 7 Iris to Earth happens on Wed Nov 4 2076 at a distance of 0.848369 Astronomical Units, or 126,914,157 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 7 Iris brightness
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 7 Iris, according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.
Asteroid 7 Iris rise and set times
The rise and set times are defined as the time at which the upper limb of Asteroid 7 Iris touches the horizon, considering the effect of the atmospheric refraction. As the atmospheric conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
